/* ** ** Swift/XRT hardness ratio for Mrk 421. ** Hardness ratio for this file has been calculated by splitting the data at 2.0 keV. ** ** Data taken from the automatic processing at http://www.swift.psu.edu/monitoring/ ** ** When using these data and results in publications, please reference M.C. Stroh & A.D. Falcone 2013, ApJS, 207, 28; arXiv: 1305.4949. ** ** Key: ** ** BinCenter - Center of time bin (MJD). ** BinHW - One-half of the full time bin size (days). ** FracExp - Conversion factor between bin size and observing time. ** Ratio - Source hardness ratio (2.0 - 10.0 keV)/(0.3 - 2.0 keV). ** This is also Rate2/Rate1 from the following columns. ** RatioError - 1 sigma error in the hardness ratio. ** Mode - 0 if in Windowed Timing (WT). ** 1 if in Photon Counting (PC). ** Rate1 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 0.3 - 2.0 keV band. ** RateError1 - 1 sigma error in source count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetRate1 - Background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** NetError1 - Error in the background subtracted count rate (cts/s) in the 0.3 - 2.0 keV band. ** Rate2 - The background subtracted, PSF corrected and pile-up corrected source count rate (cts/s) in the 2.0 - 10.0 keV band. ** RateError2 - 1 sigma error in source count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetRate2 - Background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** NetError2 - Error in the background subtracted count rate (cts/s) in the 2.0 - 10.0 keV band. ** ** ** Upper limits have an error listed as -1.00000. ** */ BinCenter BinHW Ratio RatioError FracExp Mode Rate1 RateError1 NetRate1 NetError1 Rate1 RateError2 NetRate2 NetError2 56775.929730 0.000246 0.14896 0.01145 1.00000 0 34.44134 0.94865 31.50980 0.86795 5.13049 0.36819 4.69619 0.33705 56775.930213 0.000237 0.15956 0.01223 0.96341 0 34.38121 0.96661 31.80659 0.89415 5.48573 0.39110 5.07606 0.36190 56775.930667 0.000217 0.17291 0.01335 1.00000 0 34.08513 1.00979 31.40425 0.93036 5.89374 0.42029 5.43148 0.38740 56775.931098 0.000214 0.16854 0.01353 1.00000 0 33.83834 1.01563 31.12562 0.93415 5.70318 0.42474 5.24340 0.39015 56775.931538 0.000226 0.16294 0.01254 1.00000 0 34.54575 0.99947 31.58342 0.91365 5.62899 0.40129 5.14113 0.36654 56775.931984 0.000220 0.16027 0.01235 1.00000 0 35.60005 1.02316 32.79732 0.94263 5.70554 0.40795 5.25007 0.37526 56775.932447 0.000243 0.14289 0.01085 1.00000 0 35.97241 0.97136 33.39524 0.90177 5.14014 0.36497 4.77187 0.33882 56775.932930 0.000240 0.15571 0.01188 0.97590 0 34.22687 0.95534 31.78100 0.88707 5.32944 0.37841 4.94861 0.35137 56775.933384 0.000214 0.16932 0.01294 1.00000 0 34.61650 1.02062 32.13631 0.94749 5.86144 0.41343 5.44148 0.38381 56775.933830 0.000231 0.15426 0.01188 1.00000 0 34.80263 0.98183 32.16990 0.90756 5.36855 0.38479 4.96252 0.35562 56775.934275 0.000214 0.17154 0.01332 0.98649 0 34.44412 1.02066 31.86423 0.94424 5.90870 0.42404 5.46817 0.39245 56775.934880 0.000391 0.16541 0.00971 0.98630 0 34.15052 0.75380 31.51051 0.69554 5.64878 0.30728 5.21219 0.28355
